The Trinity School is moving forward with a $21 million expansion plan on the Upper West Side, according to permits filed today with the city’s Department of Buildings.

Trinity is looking to add two stories atop the school’s cafeteria and an adjacent garage that was formerly part of 115 West 91st Street, the DOB records show. Robert Rogers of Rogers Partners is the architect of record.

“This addition improves the existing outdoor space with a new playroof/turf field above,” Rogers Partners said on its website.

A spokesperson for Trinity could not immediately be reached for comment.

Founded in 1709, Trinity moved to its current 139 West 91st Street location in 1895 and is one of the country’s most well-known private schools. Notable alumni include New York City Councilman Daniel Garodnick – the new chair of the city’s economic development committee and a key opponent of the Midtown East rezoning plan — and novelist Colson Whitehead.
